Originally this build was meant to have [Contagion Cloud] and [Umbral Intensify]. [Venom Dose] is just so much better especially when you can use Toxic Lash at the same time and attack from a distance with something like Pathocyst Riven Build. I also decided against the umbral so my other builds are not so limited.

A well placed detonation in Simulcrum against 20x 165 heavy gunner eximus after sporing yourself and the enemies while lash is running, (yes there's some work involved to get there) but anyway, if it doesn't die from the explosion sit back and watch the procs fly.

I run this with a 5 forma Vasca for that healing safety net.
